Abstract: Certain aspects of the present disclosure provide techniques for reporting an indication of a PHR when the UE's assigned of UL resources is insufficient to transmit both UL data and a PHR. Additionally, aspects described herein introduce a negative PHR used to indicate the UE requires additional UL resources.

Abstract: In an aspect, a network supporting client devices includes one or more network nodes implementing network functions. Such network functions enable a client device to apply a security context to communications with the network when the client device is not in a connected mode. The client device obtains a user plane key shared with a user plane network function implemented at a first network node and/or a control plane key shared with a control plane network function implemented at a second network node. The client device protects a data packet with the user plane key or a control packet with the control plane key. The data packet includes first destination information indicating the first network node and the control packet includes second destination information indicating the second network node. The client device transmits the data packet or control packet.

Abstract: Certain aspects of the present disclosure provide a method for confirming identity of a user equipment (UE) registered in both a wireless local area network (WLAN) and WWAN. A method is provided for wireless communications by a base station (BS). The method generally includes establishing communications with a first UE, wherein the UE is identified by a first set of one or more identifiers in a wide area wireless network (WWAN) and by a second set of one or more identifiers in a wide local area network (WLAN), and determining, based on the first and second set of identifiers, a UE connected to the WWAN and WLAN is the first UE

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and more specifically to differentiating physical random access channel (PRACH) procedures. An exemplary method performed by a user equipment generally includes detecting a trigger to perform a physical random access channel (PRACH) procedure, selecting, from a plurality of sets of PRACH parameters, a set of PRACH parameters to use in the PRACH procedure, based on the trigger, and performing the PRACH procedure using the selected set of PRACH parameters.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wirelessly routing packets. One method includes storing a mapping of one or more identifiers to one or more radio bearers associated with one or more destination devices. Each identifier is mapped to at least one radio bearer associated with at least one destination device. The method includes establishing an association with a network node and receiving information indicative of the mapping from the network node. The method includes determining the mapping based on the information indicative of the mapping. The method includes obtaining a first packet containing a first identifier and mapping the first packet to at least a first radio bearer associated with a first destination device based on the mapping and the first identifier. The method includes transmitting the first packet wirelessly over the at least one first radio bearer to the first destination device.

Abstract: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for allowing multiple P-RNTIs to be supported using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communication by a base station (BS) generally includes receiving, from a core network, a paging message for a user equipment (UE) comprising a paging identifier and a paging offset; determining a plurality of available paging identifiers for the UE associated with the paging offset; selecting, from the plurality of available paging identifiers, at least a first paging identifier to associate with a first UE based on the paging identifier; and paging the first UE using the first paging identifier.

Abstract: Methods and apparatus supporting multiple concurrent service contexts sharing a single connectivity context are disclosed. A device may initiate a radio link with a network node and establish a connectivity context with the network node over the radio link using a connectivity logical context of the device. The network node may receive, authenticate, and authorize context establishment requests. A first service context with a first service management entity may be established over the radio link using a first logical context of the device, where the first logical context is distinct from the connectivity logical context. Multiple service connections using multiple service contexts based on multiple logical contexts of the device may share the connectivity context and may be established over the radio link.

Abstract: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.
